Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a smart terminal. Background Art

[0002] With the rapid development of modern communication technology, smart terminals (such as smartphones, tablets, etc.) have become an indispensable part of people's daily lives. In order to meet users' needs for higher data transmission rates and more stable signal reception, the antenna design of smart terminals has become particularly important.

[0003] Antennas are key components in wireless communication systems, and their performance directly affects the communication quality of devices. However, with the continuous evolution of smart terminal design, the appearance and structure of devices are also being optimized, such as smart terminals with metal frames and back shells with metal decorative parts.

[0004] In the process of conceiving and implementing this application, the inventors found that there are at least the following problems: In order to make the smart terminal more beautiful, metal decorative parts are usually set at the camera of the back shell of the smart terminal. Due to the influence of the metal decorative parts, the antenna layout space is insufficient, and the antenna design needs to be reconstructed.

[0005] Therefore, the existing antenna design scheme is difficult to meet the communication requirements when metal decorative parts are set on the back shell of the smart terminal, and it is urgently needed to be improved and optimized.

[0078] With the rapid development of terminal technology, modern mobile phones, tablet computers and other smart terminals have generally been equipped with a variety of wireless communication capabilities, such as cellular communication, WiFi (Wireless-Fidelity), GPS (Global Positioning System) and Bluetooth. These diverse communication functions require smart terminals to be equipped with multiple antennas or antennas with multiple resonant frequencies to cover different wireless communication frequency bands. However, with the continuous advancement of smart terminal design, especially the high requirements for device appearance, such as high-quality metal casings and metal decorative parts at the rear camera shell, traditional antenna layout and design face new challenges.

[0079] Take a candy-bar phone as an example. Figure 1 This is a schematic diagram of the structure of a smart terminal without metal decorative parts at the rear camera housing. Figure 1 As shown, the antenna is arranged at the positions ①, ②, ③, and ④ of the metal frame of the straight phone. Two symmetrical slits are opened at the top and bottom of the straight phone, and two symmetrical slits are also opened on the left and right sides, and dielectrics are filled in the slits to realize the metal frame antenna. The antenna layout is mostly for the main antenna at the bottom of the phone, and the diversity antenna and GPS / WiFi small antenna at the top. Figure 2 This is a schematic diagram of the structure of setting a metal decorative piece at the camera of the rear shell of a smart terminal. Figure 2 As shown, the metal decorative parts are arranged away from the metal frame, and the antennas are arranged at positions ⑤, ⑥, ⑦, and ⑧ of the metal frame of the straight phone. Figure 1 Similarly, two symmetrical slits are opened at the top and bottom of the straight-bar mobile phone, and two symmetrical slits are also opened on the left and right sides, and dielectrics are filled in the slits to realize the metal frame antenna. However, when the metal decorative parts of the rear shell extend to the edge of the metal frame, the above antenna layout cannot meet user needs, and the antenna solution design needs to be reconstructed.

[0080] The technical content provided by this application is intended to solve the above technical problems of related technologies. In the embodiment of this application, the smart terminal includes an antenna assembly, a frame, and a metal decorative part; the frame is provided with a break and a connecting rib; the antenna assembly includes a radiator and a feed source formed by the frame between the break and the connecting rib; the target antenna in the antenna assembly located within the preset range of the metal decorative part corresponds to a frequency band greater than the low-frequency band. In the scheme of this application, a metal decorative part is provided on the surface of the rear shell of the smart terminal, and the frequency band of the antenna within the preset range of the metal decorative part is greater than the low-frequency band. The antenna scheme is reasonably designed to improve the antenna layout of the smart terminal, thereby reducing the impact of the metal decorative part on the antenna performance.

[0081] The technical solution of the present application and the technical solution of the present application are described in detail with optional embodiments below. The following optional embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. In the description of the present application, unless otherwise clearly specified and limited, each term should be understood in a broad sense in the art. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0082] Optionally, Figure 3 A schematic diagram of the structure of a smart terminal provided in the first embodiment of the present application is shown in FIG. Figure 3 As shown, the smart terminal includes: an antenna assembly 30, a frame 31 and a back shell 32; the back shell 32 covers the frame 31, and a metal decorative part is arranged on a partial surface of the back shell 32; the frame 31 is provided with a break and connecting ribs; the antenna assembly 30 includes a radiator and a feed source formed by the frame between the break and the connecting ribs, and the antenna assembly 30 is used to transmit a signal of a predetermined frequency band; optionally, the frequency band corresponding to the target antenna located within the preset range of the metal decorative part in the antenna assembly 30 is greater than the low-frequency band.

[0083] Optionally, the smart terminal can be implemented in various forms. For example, the smart terminal includes mobile terminals such as mobile phones, tablet computers, laptops, PDAs, PMPs, navigation devices, wearable devices, smart bracelets, pedometers, and fixed terminals such as digital TVs and desktop computers. Among them, the structure of the smart terminal includes an antenna assembly 30, a frame 31, and a back shell 32. The frame 31 can be a metal frame, a composite frame, or other conductive frames, which are not limited here. The back shell 32 is closely combined with the frame 31 to form the overall appearance and structure of the smart terminal. In order to improve the aesthetics and structural strength of the smart terminal, a metal decorative piece is provided on a partial surface of the back shell 32. Optionally, the smart terminal also includes: a rear camera; the metal decorative piece is located in the area corresponding to the rear camera, and the metal decorative piece is provided with at least one through hole to expose the rear camera.

[0084] Optionally, the antenna assembly 30 needs to consider the shielding effect of metal decorative parts on electromagnetic waves. Metal materials reflect and absorb electromagnetic waves, thereby affecting the radiation and receiving performance of the antenna assembly 30. Optionally, a break is opened on the frame 31, and connecting ribs are set. These breaks reduce the shielding effect of the metal on electromagnetic waves to a certain extent, so that the antenna assembly 30 can work normally. The frame part between the break and the connecting rib forms the radiator of the antenna assembly 30, and the feed source is responsible for transmitting the signal to the antenna assembly 30. Optionally, the feed source is a key component in the antenna system, responsible for transmitting the radio frequency signal to the radiator of the antenna assembly 30, or receiving the radio frequency signal from the radiator. Its main function is to effectively couple the signal from the transmission line to the antenna assembly 30, so that the antenna assembly 30 can radiate or receive electromagnetic waves. The antenna assembly 30 is used to transmit signals in a predetermined frequency band, and the predetermined frequency band includes but is not limited to low frequency, medium frequency, high frequency, medium and high frequency, ultra-high frequency, etc., which are set according to the frequency band requirements of the smart terminal for sending and receiving signals.

[0085] Optionally, the target antenna in the antenna assembly 30 that is within the preset range of the metal decorative part has a frequency band that is designed to be larger than the low frequency band. Optionally, the target antenna within the preset range of the metal decorative part is the antenna that is in contact with the metal decorative part. Since the design of the metal decorative part will affect the antenna, the frequency band of the target antenna that is in contact with the metal decorative part should be designed to be larger than the low frequency band, thereby reducing the impact of the metal decorative part on the target antenna. In one example, as in Figure 3 As shown, the metal decorative part extends to the edge of the frame 31, and the radiator of the target antenna includes the frame covered by the metal decorative part. Optionally, the frequency band of the antenna assembly 30 set on the frame in contact with the metal decorative part is larger than the low-frequency band, and needs to be set according to actual conditions, for example, it can be ultra-high frequency, medium frequency, etc. Compared with low-frequency signals, higher-frequency signals are less sensitive to metal shielding and can better penetrate the influence of metal decorative parts. Through this design, the smart terminal can ensure that the performance of the antenna is not interfered by metal decorative parts while maintaining a high-quality appearance, thereby achieving stable wireless communication.

[0086] In the above example, a metal decorative part is provided on the surface of the rear shell 32 of the smart terminal. The frequency band of the antenna within the preset range of the metal decorative part is greater than the low-frequency band. The antenna scheme is reasonably designed and the antenna layout of the smart terminal is improved, thereby reducing the influence of the metal decorative part on the antenna performance.

[0087] Optionally, Figure 4 FIG. 1 is a schematic diagram of a partial structure of an example intelligent terminal. Figure 4As shown, a first fracture is provided on the left side of the frame 31, a first connecting rib L1 is provided on the left side of the frame 31, and a first radiator 101 is formed by the frame between the first connecting rib and the first fracture; the target antenna includes a first antenna; the first antenna includes a first feed source F1 and a first tuning circuit, and the first tuning circuit connects the first feed source F1 and the first radiator 101; the first feed source F1 is used to excite the first radiator 101 to generate resonance in the intermediate frequency band.

[0088] In this example, the left frame of the frame 31 is provided with a first slit (i.e., slit 1), and the left frame of the frame 31 is provided with a first connecting rib L1. By providing these slits and connecting ribs at different positions of the frame 31, a unique structure is formed, and optionally, the frame portion between the first connecting rib and the first slit is referred to as a first radiator 101. The target antenna includes a first antenna, which is located within a preset range of the metal decorative part and contacts the metal decorative part, and the radiator of the first antenna is the first radiator 101, and the first radiator 101 is a frame contacting the metal decorative part.

[0089] Optionally, the first antenna adopts a 4*4 MIMO (Multiple Input Multiple Output) system. In a 4x4 MIMO system, signals can be sent through 4 transmitting antennas and received through 4 receiving antennas at the same time, thereby achieving higher data transmission rates and better signal coverage. By increasing the number of antennas, 4x4 MIMO technology can improve the capacity and reliability of the system while reducing signal attenuation and interference, thereby improving the performance of the wireless communication system. Optionally, MIMO technology refers to multiple-input multiple-output technology, which is a technology used in wireless communication systems to improve performance and increase data transmission rates. MIMO technology uses multiple antennas at the transmitting and receiving ends to simultaneously transmit and receive multiple data streams, effectively increasing the capacity and reliability of the wireless communication system.

[0090] Optionally, the first antenna includes a first feed source F1 and a first tuning circuit. The first tuning circuit connects the first feed source F1 and the first radiator 101 to ensure effective transmission and resonance of the signal. The first feed source F1 is used to excite the first radiator 101 to generate resonance in the intermediate frequency band, so that it has good radiation performance in the intermediate frequency band. Optionally, the frequency range of the intermediate frequency band is 300KHz-3000KHz.

[0091] Through the solution of this example, the frequency band corresponding to the antenna within the preset range of the metal decorative part is set to the medium frequency and ultra-high frequency bands, which reduces the impact of the metal decorative part on the antenna performance and improves the performance of the smart terminal.

[0092] Based on the above example, Figure 4As shown, in one example, the first tuning circuit includes: a first resonant circuit M1 and a first switch SW1 connected in series, the first resonant circuit M1 is used to adjust the bandwidth of the first antenna and the isolation between the first antenna and other antennas, and the first switch SW1 is used to tune the first antenna to improve the bandwidth and performance of the first antenna.

[0093] In this example, the first tuning circuit includes a first resonant circuit M1 and a first switch SW1 connected in series. One end of the first resonant circuit M1 is connected to the first radiator 101, the other end of the first resonant circuit M1 is connected to one end of the first switch SW1, and the other end of the first switch SW1 is connected to the first feed source F1.

[0094] Optionally, the main function of the first resonant circuit M1 is to adjust the bandwidth of the first antenna and the isolation between it and other antennas, so as to optimize the quality and stability of signal transmission. Through precise resonance adjustment, the first resonant circuit M1 can effectively reduce interference and noise and improve the purity and strength of the signal. The first resonant circuit M1 can be implemented by an LC component, in which the inductor and the capacitor work together to form a resonant circuit. At the same time, the first switch SW1 is used to tune the first antenna to improve the bandwidth and performance of the first antenna.
